Hi guys, I got my LG G2 a few months ago and it was my first android phone. Since I always jailbroke my apple devices I decided to root my lg g2. Everything worked fine until last week when I was prompted to install a software update. I thought this might mess up the phone since it was rooted so I postponed it until later in the day to give me time to research, but I forgot to postpone the update again and it went through at the scheduled time. Now when I turn my phone on, the lg logo is displayed, and then I get a boot certification verify error. I don't really know what that means but I can't do anything, no recovery, no download mode. I started to follow this tutorial but am stuck at what files to download. I do not know if I have the 10b, 11a, or 12b variant, and I can't find a way to check it without turning the phone on, which I can't do. I'm really lost at what to do at this point, I can't follow the only guide that might fix my phone. Is there another way to solve this issue or find which variant I have? Would verizon accept it back to fix or replace it since it's been rooted? I've read some people saying they unrooted their phone and then returned it to the carrier, is it possible to do that in my situation? I really need some help guys.
TBH: I would call Verizon, and tell them the phone was bricked by the update- hope they don't notice it was rooted when they warranty it. Problem is, if they do you get charged full amount for phone. I'd consider if you have insurance to just claim it on insurance.
try download lg support tool from lg website http://www.lg.com/uk/support/software-manuals
plug the device and wait for the software to recognize ur version.
I downloaded and installed it, but it won't recognize by phone. I have installed the drivers for it
ok.
try to follow this guide http://forum.xda-developers.com/showthread.php?t=2681089
and the files download from here:http://downloads.codefi.re/autoprime/LG/LG_G2/VS980/Stock_Firmware/10B_Partitions
lets try this virsion and see what happend..
download the 10B zip file and the dll file too http://downloads.codefi.re/autoprime/LG/LG_G2/VS980/Stock_Firmware
now it doesn't boot at all, not even to the lg logo. Additionally the partitions don't show up in ubuntu any more. I guess i'm completely screwed now?

I can get into download mode, but have a secure boot error and cant use ADB or fastboot. I've been reading every thread I can find.
I tried the LG tool, it never downloads the firmware, just hangs at 12%. Tried different drivers etc. Let it run overnight just in case it was a slow download - nada.
Tried the LG tool by entering the imei number first, but the tool reports a low battery and won't load the firmware. Phone is fully charged, i assume that battery level reporting is not working correctly.
Tried to load the kdz with the R&D tool, it errors out at 49%.
Tried to do the offline process with shttp from the unbrick any phone thread. It uses an older version of the LG tool and won't recognize that the phone is plugged in. If i install the newer tool that sees the phone, the process crashes the tool.
it all started when i tried to flash twrp and used the one for a different model g2. Dumb, I know. this is my first time soft-bricking a device.
Can anyone please point me in another direction?
UPDATE: phone was reporting that it was an 802. Downloaded and flashed an 802 kdz file and the phone booted! First time it was able to get past 49%. Nothing really works on the phone, but now i'm able to use the LG Mobile support tool to flash the correct firmware. The program is downloading the sofware now.
When you say LG tool I'm assuming you're talking about the official program you can download from their site?
I have the Verizon G2 and promptly erased everything on it the first night I got it.. Don't flash / wipe files at 4 AM when you've been up all day and night.
Anyway this thread http://forum.xda-developers.com/showthread.php?t=2432476 really saved my rear. Maybe the T-Mobile version will work to get yours back to stock.

works at the start and hangs at 49%. There is one bit that needs to be switched and this would work.
okay, looks like the phone is reporting that it is a d802 from my first f'd up flash. I think this may be causing the problems with flashing the 801 kdz.
Can i flash an 802 kdz onto an 801? then possibly later go back to 801?
Hi Friends,
I am new to this Forum and Android as well. I recently bought unlocked LG G2 32 GB in India. It was:
Model - D802
Android version - 4.4.2
Software version D80220b
As it's wifi reception and network reception was not good, I thought of installing the ROM again. The biggest mistake that I did not install any recovery and didn't even rooted my device. I checked with root checker and it showed that your device is not rooted. Then I follow the method given on below link:
http://forum.xda-developers.com/showthread.php?t=2432476
I took the firmware file named "India 32GB D80210C_00.kdz" and select type as "3GQCT" and performed the Normal Flash. It went well but after it booted up, my touch screen calibration was totally lost. I connected mouse using USB OTG cable and calibrated the device but it didn't work out. Calibration still seemed gone.
After all try, I couldn't do much and read of TOT method to go back on Jelly Bean. I did that as well using "BIN_LGD802AT-00-V10b-SEA-XX-SEP-04-2013-32G+0.exe" from which I extracted the TOT file and performed the flashing again by coming in "Download mode".
After that my phone is in boot loop and same issue of lost screen calibration. If I try to go into recovery it gives me option only to factory reset the phone which does not help out at all. I guess it's because i didn't root my phone and didn't even installed any recovery.
I know I have done a lot of mess with no knowledge but please help me out as its my new phone and I have hardly used it for 1 month and it's not even under warranty.
Thanks.

There might have been a problem with the firmware that you used and the flash method. Use this to find your firmware and pick cse flash this might solve it.
I searched the firmware in your given link by my IMEI number, but I have a problem. After I click on "Upgrade start" in "Normal web test upgrade", it does not give me country select option. Instead it open LG Mobile support tool which just keeps on showing "Waiting for Connection".
If I click start upgrade without selecting "normal web upgrade test", it gives me country selection window.
What should I do? Can I directly click on "Start upgrade" ?

OP I have the same problem, see my recent posts. Let me know if you found a fix.
Hey all,
Having a small issue with my Verizon LG G2.
When I first got it on launch, I rooted it, installed loki (to bypass the locked boot loader) and have been running custom ROMs.
This is the way I ahve been running it since, on 12B, with loki and CM11.
Before I installed custom roms I did a image backup using Clockwork.
Yesterday I bought a Droid Turbo, so it was time to restore the G2 in preparation for sale.
I attempted to restore my original backup of the stock image, but it failed (stating something about an inability to restore/system, resulting in a soft bricked phone.
I fixed this by downloading the LG Flash tool, and the stock 24A .kdz image, putting the phone in download mode and flashing it.
The LG flash tool seemed a bit buggy, complaining about not finding servers, but eventually flashed the phone with the .kdz.
Everything seems to have worked well. Root is gone, clockwork is gone, (and I assume loki is gone as well, but I can't tell) but now I can not do the latest OTA updates, and am stuck on 24A.
It's not that it downloads the OTA, and then fails to install it, but rather it complains that it is unable to download the updates at all.
I was thinking this might have something to do with the fact that the CDMA radio is now unactivated (since I got a new phone) and it somehow needs to verify with the Verizon network prior to downloading, so I grabbed a working SIM and popped it it in. Even with 4G via the SIM, the OTA downloads don't succeed.
Does the CDMA radio need to be activated in order for a phone to receive OTA updates? If not, I ahve something else wrong going on, and would appreciate any suggestions regarding fixing it.
The plan was to sell the LG G2 to pay for my Droid Turbo upgrade, but I don't want to sell the phone to someone if I think it may be having issues.
I would appreciate any thoughts and suggestions from you guys!
Hi all i have a rooted 5.0.1 Lg 340n that i tried installing twrp from the app! the c50 one! so i tried going in the recovery mode and i got a message Secure boot error i cant do factory reset or enter stock recovery and i dont have backup of my recovery ! i wanna update my phone but it keeps says that message ! any help what i can do so i can simply update my phone ?
I kinda had the same issue, so unless you have a computer and the lg driver lg flashtool and stock firmware file you're basically bricked. Your best bet is to find a corporate store and get a replacement under warranty, just don't tell them you rooted. If your phone is less than 30 days old they replace it for free, if not you can pay 15 dollars to have a new one shipped to the store in about 3 business days. I feel your pain, i hope this helps.

[H918] Successful root/fastboot unlock from 10J -> No roms are flashed successfully
Hi folks, wanted to share my current state of affairs with trying (and failing) to install a new rom on my LG V2O. Here's the order of events
Received brand new sealed-in-box LG V20 from T-Mobile from a third party seller that came in firmware 10J
Followed all directions to successfully perform dirtycow unlock
Installed TWRP (3.0.2-1)
Backed up, but mistakenly deleted the backup after trying to install Megarom in an attempt to do a clean flash
.zip flashed correctly, but hits boot loop upon reaching LG screen (even after waiting 20+ minutes on first boot). T-mobile screen never pops up
Can access TWRP still and ADB commands
Basically now, I've tried looking at as many H918 rom threads as I could but every single rom I try either: never completes flashing OR if it does complete flashing, the device never boots (either bootloop or stuck on the LG screen). I've never seen the device get past the LG screen for any reason. I am desperate for help on this matter as I have royally screwed up trying to provide a nice gift for my partner but was apparently way in over my head with trying to get a fresh rom on this thing.
Can anyone provide assistance as to how I can roll back to a stock rom? I'd be willing to give up root/recovery. All of this was spawned from wanting to be able to unlock the carrier but I have decided I'll just pay for the sim-unlock service if I can get this back to stock. Would be willing to provide some PayPal cash for someone who can help me out with this matter.
Flash to 10j kdz firmware located in the thread with all the firmwares. You`ll need lgup to flash it.
